Stark Unveils Cascade and Gambit Drones Eight Months After Flunking Every Strike in Military Trials

German defense startup Stark announced two new loitering munitions on June 8: the tube-launched Cascade and the man-portable quadcopter Gambit, revealed two days before the ILA Berlin air show opens. The timing caps a turnaround story DroneXL has tracked since October 2025, when the company’s flagship Virtus drone failed all four strike attempts during demonstrations with British and German forces.

Cascade flies 40 to 100 kilometers (25 to 62 miles) depending on battery configuration and launches from a tube in under a minute. Gambit comes in strike and reconnaissance variants light enough for one soldier to carry. Both plug into Minerva, Stark’s command-and-control software, and both navigate without GPS. Stark paired the reveal with a UK partnership: Hampshire engineering firm Force Development Services will build a six-cell launcher for Cascade, and the announcement landed days after Prime Minister Keir Starmer toured Stark’s Swindon factory.

Cascade Packs More Than Ten Launchers Onto a Single Vehicle

Cascade is a tube-launched, one-way effector with selectable ranges of 40, 60, or 100 kilometers (25, 37, or 62 miles) depending on battery configuration, a payload of up to 4.5 kilograms (10 pounds), and a deployment time the company puts at under one minute. Stark designates it OWE-T, for one-way effector, tube-launched.

The official spec sheet lists a cruise speed of 100 km/h (62 mph), a dive speed of up to 220 km/h (137 mph), and a flight time of up to 60 minutes. The launcher and effector together weigh under 20 kilograms (44 pounds), and Stark says more than ten complete systems fit on one vehicle. That math matters: a single pickup truck becomes a salvo platform for small mobile units, which is the entire pitch. Cascade is built to launch multiple effectors at once and overwhelm air defenses through simultaneous approaches.

Launch options run from a single ground tube to integrated canisters on vehicles and vessels to stationary container systems. Stark has already fired Cascade from its Vanta uncrewed surface vessel, and the Force Development Services six-cell launcher extends that to land and naval platforms, UK Defence Journal reports. A software-defined architecture allows over-the-air updates, while onboard AI and sensor fusion handle navigation, object recognition, and terminal guidance in GNSS-denied environments.

Stark CTO Johannes Schaback framed both products as direct lessons from Ukraine, telling Aviation Week in a statement that “armed forces need capabilities that can be produced quickly, adapted rapidly and fielded at scale.”

Gambit Brings Ukraine’s Fiber-Optic Lesson Into a NATO Catalog

Gambit is a foldable quadcopter sold in two variants: a strike version with a 25-kilometer (15.5-mile) range and a warhead under 2 kilograms (4.4 pounds), and a reconnaissance version that swaps the warhead for an electro-optical and infrared sensor and reaches 40 kilometers (25 miles).

The strike variant has a maximum takeoff weight of 6 kilograms (13.2 pounds), per Stark’s product page. The reconnaissance version is lighter at 4 to 4.5 kilograms (8.8 to 9.9 pounds) and flies for more than 50 minutes, against under 25 minutes for the armed version. Cruise speed is 60 km/h (37 mph), dive speed 120 km/h (75 mph), and deployment takes under five minutes. One operator carries and flies the whole system.

The detail that caught my eye is the optional fiber-optic guidance. A hair-thin cable replaces the radio link entirely, which makes jamming irrelevant. DroneXL has covered fiber-tethered FPV drones since Ukraine fielded the first jamming-resistant combat version in December 2024, and the technology has since spread far enough that spool prices have jumped more than eightfold. What started as workshop improvisation on the Donbas front is now a checkbox option in a German defense catalog.

Gambit also stands apart from most loitering munitions in one practical respect: it comes home. A NATO STANAG-compliant fuze and human-in-the-loop control let an operator abort a mission and recover the aircraft at its launch point instead of writing it off.

Stark Rebuilt Its Strike Record Between October and February

Stark enters this product launch with a trial history that swung from embarrassment to procurement in four months, a sequence DroneXL covered step by step as the company moved from failed demonstrations to signed framework agreements with the German Bundeswehr.

In October 2025, the Financial Times reported that Virtus failed to score a single legitimate hit across four strike attempts in trials with British and German forces. By December, Bundeswehr evaluations at the Altmark training center told a different story, with Inspector General Carsten Breuer citing hit probabilities above 90 percent for both Virtus and Helsing’s HX-2. In January, Helsing and Stark beat Rheinmetall to loitering munition orders worth roughly 300 million euros each, and in February the Bundestag budget committee approved the framework agreements while cutting the long-term ceiling from 4.3 billion to 2 billion euros.

The company behind all this is barely two years old. Co-founded in 2024 by Quantum Systems CEO Florian Seibel and now run by Project A co-founder Uwe Horstmann, Stark raised a Sequoia-led round in August 2025 at a valuation near $500 million and today operates in Germany, Ukraine, the UK, Sweden, and Greece.

DroneXL’s Take

I wrote the October story about Virtus missing every target, and I will admit the comeback arc has been faster than I expected. Eight months from a very public faceplant to a two-product launch and a UK launcher partnership is a pace legacy primes do not move at. Whether the hardware matches the spec sheets is a separate question, and the October episode is exactly why spec sheets from this company deserve scrutiny until independent trial data exists for Cascade and Gambit specifically.

The fiber-optic option on Gambit is the most telling line item in either announcement. Ukraine proved the concept under fire, Russia copied it, Hezbollah imported it to Lebanon, and now a Berlin startup sells it to NATO as a factory option. That transfer, from improvised battlefield workaround to Western product catalog, happened in about eighteen months.

Watch ILA Berlin, which runs June 10 to 14, for whether Stark shows live launcher hardware or stays with renders and mockups. The bigger open question is procurement: the existing Bundeswehr framework covers Virtus, and whether Cascade or Gambit earn a path into German or British orders is exactly that, an open question, not a prediction. Stark did not announce a launch customer for either system, and that absence is worth noticing.
